Abstract
We develop a tractable equilibrium pricing model to explain observed characteristics in equity returns, VIX futures, S&P 500 options, and VIX options data based on affine jump-diffusive state dynamics and representative agents endowed with Duffie-Epstein recursive preferences. Our calibrated model replicates consumption, dividends, and asset market data, including VIX futures returns, the average implied volatilities in SPX and VIX options, and first- and higher-order moments of VIX options returns. We document a time variation in the shape of VIX-option-implied volatility and a time-varying hedging relationship between VIX and SPX options that our model both captures.
